EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 535,209, dated March 5, 1895.

Application filed October 13, 1893. $eria1No.488,047. (No model.) Patented in Germany fleptember 27, 1892, No. 64,732.

To aZZ whom it may concern:

Be it known that I, FRANZ KETTHAUS, of Berlin, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Extensible Tables, (for which I have obtained a patent in Germany, No. 64,732, dated September 27, 1892,) of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to extensible tables such as are used for dining rooms and for other analogous purposes.

I obtain any required degree of extension within the limits of constructionby means of a system or systems of folding slats arranged in a manner made familiar in the well known examples of roller shutters and cylinder desks. By this means I can obtain any desired degree of extension and am not limited to the width of one or more leaves. I do not however roll the slats around a roller as in the examples cited, but arrange them under and parallel with the table top when not in use.

Iwill describe my invention with reference to the accompanying drawings, in which- Figure 1 is a plan of the extended table as seen from below. Fig. 2 is a longitudinal section of Fig. 1, and Fig. 3 is a longitudinal section of the table closed up.

The folding slats may be constructed in any suitable manner of any suitable material and are analogous with the folding slats used in roller blinds and shutters, and they may be used at one end, but preferably at both ends of the table. As represented in the drawings, the folding slats c d are employed at each end of the table to which they arejoined or hinged.

At each end of the table top a, there is a ledge 72, at the ends of which there is mounted in the brackets h, the roller Z, over which the flexible sheet of slats passes from the end of the table top a to which it is connected. If then the ledge h be pulled away from the table top a, the flexible sheet of slats will pass over the rollerZ and form an extension of the table top. (Figs. 1 and 2.) The ledge h with the roller Z and brackets h is carried on the rails m, which slide in grooves formed in the cross rails 10 below the table top a, and are thus supported horizontally. Additional sup port for the extension may if desired be obtained by auxiliary legs as hereinafter described.

The part of the flexible sheet of slats not in use is arranged to slide below the table top, instead of being wound upon a roller.

The drawings illustrate a method for drawing out the extension to its fullest extent by means of chains or the like. If such an arrangement be not used, the flexible sheet of slats can be drawn out only to the point where thelast slat is still guided underneath the table top a. With the chains however, if the slats be wholly drawn out from below the table top, they are guided back again into the grooves in which they are there contained.

In the arrangement illustrated, the chains 2' and It, are fastened below the table top ato and 0 respectively. b (Fig. 2.) From their points of connection they run respectively to and round the rollers me which are mounted upon the angle brackets r r. Thence, one pair of chains passes direct to the hooks c on the end of the flexible sheet 0, and the other pair of chains it, passes round the rollers q, back to and around the rollers o and thence to the hooks d of the flexible sheet at. The long brackets r r to which the pulleys 'n n are secured are connected with and move with the ledges h, and may serve as additional supporting rails corresponding with m m. When the extension therefore is pulled out, the rollers -n n participate in the movement, and also when the ledges are pushed in, and the chains follow or lead the extension as the case may be. When the extension is pushed in, the chains naturally lead the flexible sheet into the grooves under the table top, in which they are contained. These grooves are naturally made in two planes one above the other as shown by Figs. 2 and 3, so that they cannot come into contact and interfere with each other. The ledges f Fig. 2, are employed to sepa rate the flexible sheets under the table, and serve for the purpose efficiently but I may use any other arrangement. When it is desired to provide an additional support for the extension, I provide hinged legs y y on the ledge 0r ledges h, which when the extension is out of use may be folded up under the table top, below the flexible sheets of slats c d. When required for use, these legs may be turned down on their hinges or pivots t, by which action the notched plate 10 is engaged with the catch or plate w. (Figs. 1 and 2.) The legs are held firmly both in the horizontal and in the vertical positions by means of the spring pin or catch a: which is pressed into a hole or recess in the bracket :20. These legs give the table firmness when the extensions are drawn fully out, which is absent in ordinary extensible tables under the same condition.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. An extensible table comprising flexible end sheets of slats and ledges located on the table-frame whereby the sheets are supported one above the other when the table is pressed together; and means for drawing the sheets within the table substantially as described.

2. The combination of a table having a top a, the end ledges it having brackets 72/ the rollers I mounted in the brackets, the sheets of slats connected to the table-top and passing over and under the rollers, the sliding rails m on which the ledges are supported, and the upper and lower ledges f whereby the sheets are supported one above the other when the table is pressed together; substantially as described.

3. The combination of a table having a top a the end ledges h having brackets h, the rollers Z mounted in the brackets, the sheets of slats, connected to the table-top and passing over and under the rollers and having I hooks c, d, the sliding rails m on which the ledges are supported, the upper and lower ledges f whereby the sheets are supported one above the other when the table is pressed together, the sliding angle brackets r, r, with which the ledges are connected, having pulleys n n at their inner ends, the rollers q 11 secured to the table-frame, the chains e' secured to the hooks c passing over the pulleys n and secured to the table and the chains is secured to the hooks d passing under and over the rollers 11, q, and pulleys n and secured to the table; substantially as described.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

FRANZ KETTH AUS.
